I realised ages ago that whilst I could put together a rudimentary digital circuit I was clueless when it comes to analogue audio. This board is just great and perfect for me. Steve was also really helpful with shipping. I plan to put it inside an 80's digital guitar for built-in effects and it is just the right size, sounds great and plays nicely with other Arduino boards and the IDE (I have connected them over serial). The only downside for me was the import costs, but that was to be expected. Well worth the money to get programmable guitar effects.
I am developing synths on the Teensy audio platform. So I tried to get my port of the MDAPiano and Dexed to bring onto the TGA. I only needed to make some small additions to the used DAC in the code and it works! Now I just have to add small changes for the controllers to the code. I will release everything the next month. If you are curious you can check out the demo code at https://source.parasitstudio.de:63000/wirtz/BA_MicroMDAEPiano.git. The code ready for using will be released at https://codeberg.org/dcoredump.
Did not take long to get up and running with this board and a teensy 3.6! Timely shipping too.
Great user guide/ documentation, quality board and example codes/ library. Was able to use the Blackaddr example codes and the Teensy visual audio dsp programming tool to make a variety of effects!
Was able to use the pins on this board to add buttons/ rotary encoders, the PC based MIDI controller was great too. I would recommend this hardware for Teensy audio over trying to design your own instrument pre-amp & codec circuit. I have followed schematics for other projects and built my own pre-amps to interface my guitar with a Teensy 3.6, always had noise issues. Blackaddr nailed it, no noise at all. Well designed circuit. One could use this platform for a great variety of audio projects. Sounded awesome as a programmable guitar pedal, which is how I chose to use it.
A very well produced sound card. Sound quality is amazing. Combines perfectly with teensy micro-controller boards; Bundled with its own example source code, and all the existing teensy audio library example source code, it is a perfect environment for developing digital audio effect processors. It's perfect for beginners and experienced engineers alike.
It is clear that this product was created with love. Blackaddr has been very responsive to all the questions I've email him.
